For multiport USB MIDI interfaces, the ports are subdevices of one midi device. This isn't a problem with programs using the ALSA API, but when you want to use the OSS-compatible /dev/midiX ports, you cannot access any subdevices other than the first directly. The mapping of OSS MIDI devices to ALSA MIDI devices is as follows: /dev/midi0 -> card 0, device 0, subdevice 0 /dev/amidi0 -> card 0, device 1, subdevice 0 /dev/midi1 -> card 1, device 0, subdevice 0 /dev/amidi1 -> card 1, device 1, subdevice 0 /dev/midi2 -> card 2, device 0, subdevice 0 /dev/amidi2 -> card 2, device 1, subdevice 0 ... > If this is the case, then how do I access the second port. You can load the snd-virmidi driver to create a virtual soundcard having its own MIDI device, and then connect this port to the 2x2's second MIDI port (with aconnect). > In this situation the hdsp is not in use, so midisport assumes the 2nd > card position. > ... > options snd-usb-audio vid=0x763 pid=0x1001 index=2 It shouldn't, because the above options line tells the driver to load at index 2. And if you'd use 0x1110 as product ID, it actually would. ;-) (0x1001 is the ID of the device without firmware.)
